After the latest update: Every time I send a message and have selected at recipient, the program searches for a cetificate, allthough encryption is swichted off. A box appears for each recipient for about a minute, unless I stop the search (see image). Essentially, the program acts, as if I had selected encryption. This was newer an issue before latest update.

I was subscribed to a large distribution list, but then unsubscribed. But I didn't unsubscribe. So I subscribed again, but was soon unsubscribed again! My email address and password may have been hacked. So I logged into my Comcast ISP and changed my email password. Then I started Thunderbird, and as expected, it asked for my password, and I gave it. My email came up. I tried sending an email and it asked for a sending password. I ignored it, but after a long delay, it refused to send the message. So I tried again, this time giving it my new email password. The sending then worked. I assumed all was now OK.

But, as a final test, I exited Thunderbird, and then restarted. It again came up OK with my emails shown. Then I again tried sending a test message to myself. But it again asked for my sending password! Thinking this might be a scam, I put in a password of "bullshit". Then I received the following popup message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Polite people say HELO first. Please verify that your email address is correct in your account settings and try again.

What!!! It sure seems like someone (at Thunderbird?) is in the loop grabbing my password before encoding it for storage. A similar thing happened in the past, where I think my account was hacked. So, was this a hacking attempt, and if so, was it from Thunderbird software or my Comcast ISP?

I have 4 e-mail accounts in TB, and I want to switch from the current default account to another. But how do I do that. I cannot see any button, place where to do that in the settings. Why the heck does TB needs to be so tricky to deal with, compared to Outlook?

I am having issues with Thunderbird not retaining my email server and passwords. Each time I want to send an email, it prompts me for the password and then tells me that the email address and server don't match. I have tried numerous times to correct this, but it doesn't hold the information. It also switches the server info between accounts. I have 3 different email account and sometimes only one works correctly

I had someone breaking into a number of my accounts. They used my account to sign into Firefox. And I got an account authorization code, but I'm afraid to use the email in case it is them getting more info!!

Hi. with Firefox not able to get default colors on twitter. With other browser no problem - i've got default colors All Extensions disabled, restarted - but no change

I've got notifications informing me with various sentences. That my account has been hacked, Scammers have your passwords, your card details have been stolen. These messages are only in Notifications not one email received. I feel they are scams. Anyone else had this. All my accounts are locked down so I'm not alarmed. And all is fine. Anyone out there that can offer their experience? Thanks

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

This is almost surely a "security" or "privacy" design, but it's an error. In Firefox - only (this works fine in Chrome) - if I open the LastPass Firefox Extension, find a Site, and Copy the password, then go directly to an open AnyDesk remote access connection, and Paste (or, lightning bolt menu, Insert from Clipboard), what gets pasted is a single wrong character, NOT the password that IS in the clipboard. (If I paste instead into e.g. a local Notepad window, the actual password gets pasted). I asked AnyDesk support about this, and they confirmed that it's something that Firefox is doing. It shouldn't. Copy is copy. Paste is paste. Why would Firefox do something so that copied text (which just happens to be a password from a password vault extension) pastes wrong when the destination just happens to be a remote desktop client (AnyDesk) to send the password through to complete a login at the remote end? Anyway, how to turn off this wrong behaviour? thank you. (Windows 11 Pro, 64-bit, 23H2, Firefox current - 125.something today, but this has been going on for some weeks at least, AnyDesk version 8 current)

thank you for taking out my new real email that I wish to use a sign-in ID I read the ibstructions to not leave personal info.But I was wondering how Iwould get an answer -- and of course I just have to check back here regulary. If Mr. Moderrator you know a link to solve my problem I would appreciate.

Sincere Thanks Paul

Windows 10 --22H2 ---Sorry.

We are using three locations to send emails from this email address. One of the computers at one home, sometime in mid April, was put into a block of some kind for having a PUP (the best I can figure out, don't really understand this stuff.) We had the block removed and most emails are now going through from that one computer. The other computers never had a problem getting their emails to the recipients. The one computer that had trouble, now has Maleware Bytes and Adwcleaner installed, that's what we did to get out of email jail I guess.

The problem is, any of the people that we attempted to email during the week or so that our email was in jail, even though it is fixed, our emails to those people are not getting to them still. We have to use another email address to get them to receive from thunderbird sent from our one computer.

We are not super computer savvy as far as this behind the scenes computer technology goes and need help so that we can reach all our customers reliably. We did try to identify if we were still blacklisted and saw 1 hit but don't understand how to fix it now that we have the additional spyware type stuff added to our computer. Your assistance would be greatly appreciated.

Thank you
